Alice Walker's most famous work, THE COLOR PURPLE (1982), takes the form, unusual in modern-day Western literature, of an epistolary novel. The story is told in letters, many of them addressed to God by the novel's protagonist, Celie, a young black girl in rural Georgia. zav | Student, Undergraduate | eNotes Newbie.
What happens after a supernova? A: Depending on the size of the star before it explodes as a supernova, the core of the star either shrinks back into a tiny neutron star or becomes a black hole. If the star is only a few times bigger than the sun, the core becomes a tiny neutron star.
Because Type Ia supernovas all occur in a star that has a mass of about 1.4 solar masses, they produce about the same amount of light. This property makes them extremely useful as a distance indicator - if one Type Ia supernova is dimmer than another one, it must be further away by an amount that can be calculated. In recent years Type Ia supernova have been used in this way to determine the rate of expansion of the universe. This research has led to the astounding discovery that the expansion of the universe is accelerating, possibly because the universe is filled with a mysterious substance called dark energy.
